Reputation is what other people think of you based on your past actions and behavior. It's the story that follows you around: whether people see you as honest or sneaky, reliable or flaky, kind or mean.

Your reputation builds up over time through the choices you make. If you always turn in careful work, help classmates who are struggling, and keep your promises, you build a reputation as someone trustworthy and capable. If you constantly make excuses, blame others when things go wrong, or gossip behind people's backs, you develop a different kind of reputation entirely.

Here's what makes reputation powerful: it shapes how people treat you before they even know you well. A student with a reputation for being a good team player gets picked first for group projects. A store with a reputation for fair prices and quality goods attracts more customers. A doctor with a reputation for careful diagnosis gets more patients.

Reputation can be fragile. You might spend years building a reputation for honesty, but one big lie can damage it severely. That's why people say it takes a lifetime to build a good reputation but only a moment to destroy it. The flip side is also true: even if you've made mistakes, you can rebuild your reputation through consistent good behavior over time.

A reputable person or business has earned a good reputation through reliable, honest behavior.
